AUTOMATIC STOKER.

. Specification of Letters Patent.

Patented Dec. as, 19115.

Application filed May 18, 1915. Serial No. 28,812.

To all whom it may concern Be it known that I, DAVID T. WILLIAMS, a subject of the King of England, residing at Paterson, in the county of 'Passaic and Stateof New Jersey, have invented certain reached and broken down by the fireman tender, the

new and useful Improvements in Automatic Stokers, of which the following is a specification...

Thisfinventiona'elates to automatic stoking apparatus, and it consists in an improvement upon the stoking apparatus set forth in my application Serial- Number 805,021, wherein the novel feature was an abutment means coactive with the means for advancing the fuel (such as a screw) in a fuel bun- 'ker to exert reducing pressure on the fuel;

In the illustrated embodiment. in that case, where the advancing means extended under one of the upright supports (of the bunker) for the fuel, specifically, hinged doors and planking below the doors, the abutment means was located inapproximately the same plane as said support, and this led to the difficulty that if thefuel packed in archformation overthe screw and at the abutment means when the bunker was more or less full the fireman did not have easy manual access to the jam to break it down and thus cause-the operation to proceed inthe regular way.

My present invention is designed to overcome thi s difficulty, .and this I. accomplish by placing the abutment means a suitable I distance forward of the aforesaid support, so that if a jam occurs at the front of the bunker it will be exposed and may be easily with a poker or other suitable implement.

Inthe accompanying drawings, Figure 1 shows the invention applied to a locomotive parts appearing in vertical longi-' tudinal central section; Fig. 2 is a plan of what is shown in Fig. '1, the forward side portions of the tender appearing in horizontal section; and, Fig. 3 is a vertical sectional view on line xx of Fig. 1, looking in the direction of the arrow in said figure.

The locomotive tender bunker a has its bottom Z) V-shaped in cross-section (Fig. 3), this formation reaching from the vertical rear wall 0 forward into the narrow space between the tool boxes (1 at the forward part of the tender to the vertical wall 6. Alined with the bottom of the bunker a is the bottom of the trough 7, which is substantially U-shaped in cross-section and extends forward to the front end of the tendeI'; communication between this trough and the bunker is afforded through 'a U- shapcd opening 9 formed in wall 6.

In bearings h and i is journaled the horizontal screw section 7', arranged longitudinally of and at the bottoms of the bunker and trough; it forms a part of a screw fuel advancing means, the forward part of which is not shown, being carried by the locomotive.

is designates planking arranged in the vertical guides Z and forming part of the forward-support for the fuel in the bunker; it is preferably removable, so that the fireman may enter' the bunker. It is obvious that the nature and construction of this forward support are not material. The wall e,"

it will be noted, is arranged a suitable distance forward of thev support is.

m is the deck of the tender, reachingfrom a point forward of the tool boxes (1 back to the wall 6 and having the part m thereof directly over the trough f a removable portion, forming a cover for the trough. From wall 6 to the support is the screw is exposed by an opening 71., which in the present case is as wide as the distance between. the tool-boxes and is shown without removable covering means, although that is immaterial.

To the wall e is bolted the fuel abutment means coactive with the screw for exerting as in my application aforesaidand having 1 V an opening 0 receiving the screw.

In view of this description and the draw ings, it will be apparent that should the fuel in the bunker jam as by the larger coal lumps forming an arch over the screw, the bunker being more or less full and it being impossible or ditlicult to have access to the jam behind the support is, access may readily be had to breakthe jam with a poker or other suitable implement through the opening a.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A fuel conveying means for automatic stokersincluding means to advance the fuel in a'substantially horizontal course, a relaover and spaced from the advancing means, and means against which reducing pressure is exerted-by the advancing means on the fuel ,while the'latter is being advanced in said course, the last-named means extending over the advancing means and being relatively forward of and spaced from said support and affording between itself and the latter-clear access to the body of fuel.

2. Incombination, a fuel bunkerhaving an upright support for the fuel, means to advance the fuel in a forward course under said support and over the bottom of the,

from said support and affording between itself and the latter clear access to the'body of fuel. I

8. I11 combination, a fuel bunker having an upright support for the fLl8l,'-II1Q1I1S to advance the fuel in a forwardlcourse under said support and over the bottom ofthe bunker, means against which reducing pressure is exerted on the. fuel said advancing means while the fuel is being advanced in saidcourse, the last-named means extending overthe advancing means and being relatively forward of and spaced from said support and affording between itself and the latter clear access to the body of fuel, and a deck extending forwardly sub stantially from said last-named means.

In testimony whereof I aflix my signature.

DAVID T. WILLIAMS.
